Title: Grinding and sieving device
Inventor: SUGIMORI TERUHIKO
IPC: B07B1/22
Filed: 1985-09-17
Abstract: PURPOSE:To obtain particulate polymer, which contains little dust-size particles and the range of the particle size distribution of which is narrow, by a structure wherein a device to grind an sieve soft coagulation consists of a semicylindrical fixed wire net and a cylindrical rotating wire net, the meshes of both of which lie within the specified ranges respectively and the minimum gap between both nets is specified. CONSTITUTION:In a device to grind and sieve soft coagulation, which is obtained by bringing polymer latex into contact with coagulating liquid and has a volumetric mean particle size of 100mum or more, a semicylindrical fixed wire net 1 and a cylindrical rotating wire net 2 are installed parallel with each other. The meshes of the empolyed wire nets are respectively lie within the range of 5-50 mesh. the particle size of particulate polymer obtained by a wire net coarser than 5 mesh is too coarse. On the other hand, its particle size obtained by a wire net finer than 50 mesh is too fine and the dust-size particle becomes so large that the handling property of the resultant polymer deteriorates and the cloggings of the wire nets during running tend to occur. The minimum value of the radial gap between the fixed wire net 1 and the rotating wire net 2 is set to be 5mm or less. If the gap exceeds 5mm, the particle of the soft coagulation tends to pile up on the fixed wire net 1 and the grinding efficiency deteriorates and, in addition, dust-size particle tends to develop, because the rotating wire net 2 agitates the piled-up soft coagulation ceaselessly as a result.

Abstract: PURPOSE:To protect the deterioration in properties at both end faces of a fiber and to stably produce the above element without degrading the incident coupling efficiency of basic waves by applying a specific aq. soln. on both end faces of the fiber and drying the coating to solidify, thereby forming high-polymer films. CONSTITUTION:The fiber is formed by forming a core 1 in a clad 2 and thereafter, the aq. soln. in which high polymers are dispersed and the same org. nonlinear optical material as the org. nonlinear optical material of the core is dissolved is applied on both end faces of the fiber and are solidified by drying to form the high-polymer films 3. The solubility of the org. nonlinear optical material in water is extremely small and, therefore, even if the soln. is not satd. with the nonlinear optical material, the amt. at which the core elutes in the soln. is as small as negligible. On the other hand, the amt. of the single crystal of the org. nonlinear optical material to be precipitated as small as negligible even when the soln. is supersatd. with the nonlinear optical material. The high-polymer films are formed on the end faces without changing the state of the end faces of the core in this way and, therefore, the element is produced stably without degrading the incident coupling efficiency of the basic waves.
